It has become something of an annual tradition that I produce an advent calendar each year with facts, interesting links and videos. Consider it a little festive treat for your brain :) Here is your 2016 advent calendar – check out the doors that are already open, and come back each day for a new treat!
What is the minimum amount of time it takes to fossilise something? (asked by Nick)
Fossils are defined as the remains or traces of organisms that died more than 10,000 years ago, therefore, by definition the minimum time it takes to make a fossil is 10,000 years. But, that is just an arbitrary line in the sand – it means very little in terms of the fossilisation process.
